  1. Introduction to piecewise functions - Khan Academy

    A piecewise function is a function built from pieces of different functions over different intervals. For example, we can make a piecewise function f (x) where f (x) = -9 when -9 < x ≤ -5, f (x) = 6 when -5 < …

  2. Worked example: graphing piecewise functions - Khan Academy

    A piecewise function is a function that is defined in separate "pieces" or intervals. For each region or interval, the function may have a different equation or rule that describes it. We can graph a …

  3. Limits of combined functions: piecewise functions - Khan Academy

    This video demonstrates that even when individual limits of functions f (x) and g (x) don't exist, the limit of their sum or product might still exist. By analyzing left and right-hand limits, we can determine if …

  4. Absolute value & piecewise functions - Math | Khan Academy

    Piecewise functions piece together different functions. Absolute value graphs make a V shape, but why do they do that? Let's explore how to make some new and interesting types of graphs. **Unit guides …

  5. Absolute value & piecewise functions: FAQ - Khan Academy

    To match a piecewise function with its value, you have to figure out which restriction your input value lies in, and then you evaluate the function that your input lies within with that value.

  6. Piecewise functions graphs | Algebra (practice) | Khan Academy

    Piecewise functions graphs VA.Math: AFDA.AF.2.h VA.Math.2023: AFDA.AF.2.h Google Classroom Microsoft Teams

  7. Limits of piecewise functions (video) | Khan Academy

    We learn that to find one-sided and two-sided limits, we need to consider the function definition for the specific interval we're approaching and substitute the value of x accordingly.

  8. Definite integral of piecewise function (video) | Khan Academy

    Sal evaluates definite integral of a piecewise function over an interval that goes through the two cases of the function.

  9. Khan Academy

    Regardless of who you are, mastering even just one more skill on Khan Academy results in learning gains.

  10. Worked example: evaluating piecewise functions - Khan Academy

    A piecewise function is a function that is defined in separate "pieces" or intervals. For each region or interval, the function may have a different equation or rule that describes it. We can evaluate …
